HENRY lv'. YQWELLQF I Application prlfG, ,1920.V Serial 170.371.645.

il .RenoQinthe'county ofCanadian endg-@tate of klahoma, "have Ainvented :new-andusjeful 'Improvements in Mud A:Rings 'for Boilersfol which'the 'following is a specification. f

The object of Ymy present Ainventioniis-to provide va peculiar andadvantageou's mud ring construction, of "such zcharafcte'r `tliatjnnid scalejwill be :washed out oja boiler-when 'the Jsame Vis'unde'r steam'vpressure.

'To `Vthe attainment o/the- L:Eo11'going, Lvthe invention consists in' VtheI improvement hereinafter described and "definitely claimed.

In the accompanying drawings, hereby made-a lpart hereoif:

Figure `1 is ar longitudinal central vertical section of the construction constituting the best practical embodiment of my invention of which I am cognizant.

Figure 2 is a longitudinal central horizontal section of the construction, looking downwardly.

Figure 3 is a vertical central transverse section of the construction taken in the plane indicated by the line 3 3 of Figure 1 .Figure 4 is a similar view taken in the plane indicated by the line 4 4 of Figure l Figure 5 is a detail, enlarged sectiontaken in a plane immediately above one of the stretches of the mud ring.

Figures 6 and 7 are enlarged detail sec-- tions taken in the planes indicated by the lines 6 6 and 7 7, respectively, of Figure 5.V

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel construction includes two pipes 1 and 2. The upper pipe 1 is arranged on the top of the crownsheet 3 of the boiler for the purpose of washing oli any mud or scale which may settle there; it being understood in this connection that the said pipe 1 is provided at its undery side at intervals of its length with apertures 4. The lower pipe 2 is disposed in the barrel 5 of the boiler, and is designed to wash mud and scale out of the' barrel and toward the blow-ot valve, indicated by 6. The lower pipe 2 is also provided in its under side with apertures 7,

and lboth andf2 are. loiigitudinally of the boiler. y At8 the lower pipe 12de-provided with anfarmrgthat extends to 'tl'ieoutsidefQf thefboifler, asfslro'wnf l Located ibetween and :connected by fri-vets itoithe l'boilersheetsatftheflower end-slof fthe e Llegsi9,-'is lthegm-ud .ring 10 "ofmy improvef ment; the Vsaid mud Lring :1'0 fbeing provided at 111 Awith an 'inlet ,f:or-fwater. Asgshown, Athe pipes and 2 fandthe .mud .ri-ngfrgl) are `interposition ibetwe'en .andeonnection to the 'boi'ler isheets. in? aits iwallplthe mind ring 10 is provided at intervals with apertures 13 over which are delecting caps 14, disposed as shown, in order to insure the flow of water inside the lower'portion of the boiler toward the blow-o valve 6, this in order to wash all mud or scale that settle on the mud ring 10 toward the blow-off valve 6, so that when'the valve 6 is opened, the foreign substances will be discharged from the boiler.

It will be apparent from the foregoing that when a boiler is equipped with my improvement, mud and scale may be washed out of the boiler when'the same is under steam pressure, by the forcing of the water through the mud ring 10 and the pipes 1 and 2, kthereby setting up a circulation of water toward the blowo valve 6, with the result that when said valve is opened, the boiler will be expeditiously and thoroughly cleaned. It will also be apparent that the arrangement of my improvement is such as to bring about agitation of mud or scale iny the boiler, and all circulation of water being' 1 in the direction of the blow-oif valve when the same is opened, the mud and scale will settle toward the said blow-ofi valve. In this connection it will be appreciated that the mud and scale, because of their specific gravity, will be washed along the bottom of the boiler formed by the mud ring 10, until the foreign substances arrive at the blow-od` valve 6, which valve will be opened during the maintenance of the circulation stated.

The feed water pump 12 is connected by pipe 31 with an appropriate source of feed water supply (not shown), and by a pipe 31X with the steam dome of the boiler, and by pipes 32 with the pipes l and 2 andthe mud ring 10. The vvalve of the pump 12 is designated by 30, and when said'valve and the valve 6 are opened water'wll be caused to pass through the pipes 1 and 2, the interior of the boiler, the mud ring 10 andthe valve Having described my invention, what I claimfand desire to secure by LettersvPatent,

The combination withl allocomotive boiler, of a hollow mud ring interposed be- Y tween and connected to the boiler sheets at the bottom of the legs and having apertures Vin its upper wall in'communication with the interior of the legs and alsohaving above said apertures caps disposed to assist 1n the Vpassage of water toward a blow-off valve 'connectedto one leg at -a point slightly above said apertures, means Jfor causing water to pass through said ring -and a blow-off valve connected with the interior of one leg of the boiler at a point above the mud ring.

vring interposed between and connected to the boiler sheets at the bottom of the legs and having apertures 1n its outer wall in Y communication with the interior of the legs and also'having caps disposed above said apertures and arranged to promote the circulation of water and the movement of mud and scale on themud ring and toward the said blow-oil7 valve, and means for causing water to pass through said ringe 4. The combination with a locomotive boiler, of an apertured mud ring connected with the legs of the boiler, a blow oli"y valve connected with the interior .of one leg vof the boiler above the mud ring,rand a pump connected to the mud ring. t
